Jiayuguan large number of manufacturers of insulation joint insulation joint stock

Jiayuguan large number of manufacturers of insulating joint insulation joint stock Product Overview: insulated joints are both buried steel pipeline requires sealing can, collectively, dielectric strength and electrical energy required corrosion of the pipe joints can. It includes assembly, insulation boards, packing, sealing rings, short sections. Structural features: Insulation extrusion welded joints with the overall pattern, shall not be used bolt flange connection type. Insulation joint use of the insulation and sealing material sandwiched and fixed to the sleeve (assembly) of the type. After insulated joint assembly, each internal component shall be fixed in the appropriate location. Under pressure in the soil, the provisions of the pipeline operating pressure and the factory or in the field of hydraulic test, the entire insulation joints intact. Insulation joint sealing element against the insulation plate inside the joint, with a permanent elastic, and both sides of the sealing element does not move in direct contact with the exposed metal surface to ensure tight joints. 2, structural features: Insulation extrusion welded joints with the overall pattern, shall not be used bolt flange connection type.
